JCP-OBS-001: Observational Validation Protocol — Directional Coherence of Cosmological Anomalies Under the Glass Onion Theorem

Description: The Glass Onion Theorem (GOT) proposes that the observable universe is a metastable crystallized geometric projection of a pre-dimensional, non-metric substrate S₀, governed by a density cascade operator D̂₀→₁ and stabilized by substrate osmotic pressure Λ_osm. We present JCP-OBS-001, a preregistered multi-channel test of the GOT framework against eight independent cosmological anomalies including the CMB hemispherical power asymmetry, the Hubble tension directional bias, the >5σ quasar dipole mismatch, and the NANOGrav gravitational wave background anisotropy. The observed coherence Ξ_obs = 0.6562 corresponds to Z = 3.08σ (p = 0.0010) against the ΛCDM isotropic null, validated by CLT derivation and N=100,000 Monte Carlo realizations. Version 5.5.2 updates: DC Master Ledger expanded to DC-028 through DC-049 (22 entries). DC-048 adds the Bellazzini et al. proof that gravity emerges as a logical necessity from massive spin-3/2 particles, providing an independent formal bridge to the SU(2) substrate framework. DC-049 adds the Liu-Quintin-Afshordi Quadratic Quantum Gravity result replacing the Big Bang singularity with a high-energy phase transition, providing independent validation for the S₀→Σ crystallization model. DC-039 footnote extended to record the DESI five-year survey completion on April 15, 2026 (47 million galaxies, 38% overage), establishing the 2027 full-survey analysis as the definitive prospective test of the Λ_osm thawing dark energy prediction. Framework content: Section 12 — U(1) Chern-Simons derivation of ξ = α/2π yielding parameter-free CMB birefringence prediction β ≈ 0.30° (LiteBIRD/CMB-S4 5–13σ test); Section 13 — Theorem 4.1 SU(2) holonomy with parameter-free β/D_excess consistency relation; Section 14 — Theorem 4.2 anyonic dark matter predicting cored halo profiles (Rubin LSST/Euclid test); Appendices C and D — null distribution validation and variational derivation.
